Description Prominently marked with gray on the cheeks, shoulders and rump. Dorsal stripes are darker than those of the Gray-footed Chipmunk. Hind feet are pinkish buff. In winter the flanks and tail edges are paler, and the belly has more gray. Runs with tail held horizontally.

Discussion Often sits on logs slowly waving tail from side to side while “chucking.” Alarm call is a shrill “chipper.” Climbs trees more than other chipmunks. Has a limited range in montane coniferous forests between 1950 and 3440m.
